Dynamic Dialog - able to see secondary choice after first level is changed

[joeobar]

Hello

I created a dynamic dialog based on the document (Adobe Experience Manager Help | Dynamically modifying an Adobe Experience Manager Touch UI Dialog​).  It seems to be functioning correctly for the most part.  My issue is when I change the drop down from A to B the secondary selections that were set under A continue to be shown with the options for B.  In the screen shots my choice is Areas of Interest, under which I select from the tags picker Topics:Labor&Employment/Employee Benefits.  If I change the drop down to Entity Membership the prior choice remains visible.  I would obviously like this to be hidden.  I have been searching through the documentation to determine how to correct but cannot find the solution.  Any assistance would be greatly appreciated.

I think I can help you but it depends on one thing: what version of AEM are you on?

[joeobar]

Thanks for the reply.  We are using 6.2 SP1.

Demo

Here is a working example of your Edit Dialog using Coral 3 (open image in a new tab if it's too small to see).

Code

Here is the XML for the demo above. Please be careful! I copied the XML you provided as a base and converted it to Coral 3 (plus some other modifications). The XML below creates an Edit Dialog that behaves the way I understood your requirement, but it will not work as-is with your component (I wasn't pedantic about name fields for example, and I renamed some nodes for my own comprehension):

Coral 2 vs Coral 3

You used Coral 2 to implement your Edit Dialog, which may be standard on 6.2 installations but is quickly going out of style for more recent releases. Consider, wherever possible, migrating to Coral 3 as it has new and better features and will future-proof your project when you decide to migrate to a newer version (which I strongly recommend by the way, I think you may be behind on several serious security fixes). You can learn more about Coral 3 here: Migration Guide to CoralUI 3-based — Granite UI 1.0 documentation.

Important: if you do decide to start using Coral 3 components, avoid creating UIs/dialogs that include a mix of Coral 2 and 3, I've seen many weird side-effects from this. You can tell Coral 2 and 3 components apart by their location in the JCR:

Coral 2: /libs/granite/ui/components/foundation

Coral 3: /libs/granite/ui/components/coral/foundation

Impact on your implementation

1. As you can see in the XML, the dynamic field show/hide functionality is now implemented with the use of granite:data nodes placed under the drop-downs (to indicate that the drop-down will trigger show/hide) and targets (to indicate that a node will be affected by the show/hide). The implementation remains largely the same, but by placing this information in separate nodes, it becomes a lot clearer and is de-coupled from the node's other properties.
   
   
2. I changed the resource type of the tag selectors and placed them inside containers. As the entire container is shown or hidden based on the drop-down selection, you won't see the selected tags of the hidden components.

I hope this helps, if it doesn't work for you (I tested this on AEM 6.5.1), please tell me
